The most common hormones that need to be checked after pregnancy include two, one is human chorionic gonadotropin and the other is progesterone. First of all, human chorionic gonadotropin, also known as HCG, usually doubles in growth every other day, for example, the HCG checked on May 20th is 100mmol/L, and the HCG rechecked on May 22nd has to grow to about 200mmol/L to be normal. Another is progesterone, progesterone is at least greater than 20ng/mL, some hospitals progesterone after the unit is nmol/L, the difference between 1ng/mL multiplied by 3.17 is equal to 1nmol/L, you can not just look at the value of the progesterone, to be converted and then see whether it is normal.
